5 bundles · 9 layers · 16 findings · 24 questions
Population identity and evidence Establishes which Guinea-Bissau population a claim describes and how that claim was produced.
Territory and population universe
Defines the country, territorial coverage and inclusion rules of each population statement.
Guinea-Bissau population boundary
Record how the source identifies Guinea-Bissau and separates residents from citizens, visitors and people living abroad.
- What country identifier, territorial coverage and residence rule establish that this claim concerns the intended Guinea-Bissau population? boundary
- How are temporarily absent residents, foreign residents and people of Guinea-Bissau origin living abroad included or excluded? definition
Source lineage and claim status
Separates direct enumeration, sample evidence, registration, estimates and projections.
Traceable demographic claim
Retain the originating publication, reference period, methodological basis and revision status behind each reported value.
- Which Guinea-Bissau census, survey, registration system or documented estimation exercise supplies the underlying evidence? provenance
- Is the value an enumeration, adjusted estimate or projection, and which edition and assumptions govern it? provenance
Population stock and spatial pattern Organises population totals and settlement patterns across Guinea-Bissau's documented geographic units.
National population and time
Relates population totals and growth measures to consistent reference dates.
Comparable population series
Treat changes between reported totals as interpretable only after checking population definitions and estimation bases.
- Which reference dates and population definitions underpin the Guinea-Bissau totals being compared? measurement
- Could a reported increase or decrease reflect revised estimation, coverage or definitions rather than population change? boundary
Bissau, mainland and islands
Preserves administrative and settlement distinctions needed for subnational interpretation.
Geographic comparability
Record the geographic meaning of Bissau and other reporting areas, including the coverage and aggregation of Bijagós island settlements.
- Does 'Bissau' denote a settlement, an administrative unit or another spatial extent in this source? boundary
- How are mainland and Bijagós populations enumerated and aggregated, and what boundary crosswalk is needed for comparison over time? measurement
Population composition and households Describes age-sex structure, household membership and explicitly measured social or linguistic affiliations.
Age-sex and household structure
Connects population composition with the source's age, sex and household definitions.
Composition and membership rules
Document cohort distributions and household membership without assuming that a household is identical to a family or dwelling.
- What age bands, sex categories and treatment of unknown ages underpin Guinea-Bissau's reported population structure? measurement
- How does the source define household membership for absent members, shared compounds and collective accommodation? definition
Language, ethnicity and religion
Keeps distinct forms of affiliation separate and tied to the questions actually asked.
Source-defined affiliation
Record language use and social identification as measured categories, preserving multiple responses and uncertainty where applicable.
- When Portuguese, Guinea-Bissau Creole or another language is reported, does the measure concern first language, home use, proficiency or another criterion? definition
- Are ethnicity and religion figures based on self-identification, proxy responses or external classification, and can respondents report multiple affiliations? provenance
Population dynamics and use Examines fertility, mortality and migration and establishes what demographic evidence can support.
Births, deaths and survival
Distinguishes event counts, rates and modelled fertility or survival measures.
Vital-process measurement
Retain the observation method, denominator and reference interval for fertility and mortality indicators.
- Are Guinea-Bissau's birth and death measures derived from registration, retrospective survey histories, census questions or demographic models? provenance
- Which population denominators, recall periods and uncertainty measures support the reported fertility, child mortality or life-expectancy indicators? measurement
Mobility, projections and decisions
Separates migration and temporary mobility and links projection assumptions to permitted interpretations.
Migration and projection limits
Record how internal movement, international migration and temporary absence enter population estimates and future scenarios.
- How does the source distinguish moves involving Bissau, mainland areas, islands and destinations abroad from seasonal mobility or temporary absence? definition
- Given its migration assumptions, geographic detail and uncertainty, can this estimate support the proposed local decision, or only a national scenario? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.

What it is Filled
The demographics of Guinea-Bissau comprise the statistical description and analysis of its human population, including its size, distribution, composition, and changes through births, deaths, and migration.
In scope
- Population size, growth and age-sex composition for explicitly defined reference dates and resident populations.
- Population distribution across Bissau, other settlements, administrative areas and the Bijagós islands.
- Fertility, mortality and migration as components of population change.
- Household composition and source-defined language, ethnicity and religious affiliation categories.
- Provenance, coverage, uncertainty and comparability of demographic observations, estimates and projections.
Out of scope
- Guinea-Bissau's geography, government and general national history except where needed to interpret demographic evidence.
- Individual residents, identifiable household records and personal migration histories.
- Demography as a general discipline, including its degrees, journals and professional institutions.
- Clinical disease profiles and health-service operations beyond their relation to population measures.
- Demographics of neighbouring Guinea, or of the Guinea-Bissau diaspora as a separate population outside an explicitly stated migration comparison.
Why it exists Filled
Enable an agent to recognise, assess and responsibly use knowledge about Guinea-Bissau's population composition, distribution and change while distinguishing observations from estimates and projections.
Distinguishing features Filled
- The subject concerns Guinea-Bissau; records labelled only 'Guinea' require country disambiguation before inclusion.
- A qualifying claim describes a defined population or demographic process, rather than merely describing a place or its institutions.
- The territorial population must be distinguished from citizens, people of Guinea-Bissau origin and people born there but living abroad.
- National and subnational comparisons must preserve the source's treatment of Bissau, island populations and administrative boundaries.
- The subject is a body of country-specific demographic knowledge, not a standalone field requiring its own professional societies or classification codes.
What robots and AI may and may not do Filled
Must not
- Present projections as observed counts.
- Rank ethnic groups by size or character in a way that feeds political rivalry.
- Treat data from a single region or the capital as representative of the whole country.
- Identify individuals from survey data in small island or rural communities.
Only with a human decision
- Publishing figures that will be used for electoral or aid planning.
May
- Report Guinea-Bissau's population figures with their source, date and estimation method.
- Note when figures come from projections rather than a recent census.
Moral aspects Filled
- Ethnic balance is politically sensitive in a country with a history of coups and instability.
- Weak statistical systems mean errors can go unchallenged and misdirect help.
Who is affected
- Residents of Guinea-Bissau
- Island and rural communities
- Ethnic communities

Capabilities and actions required Filled
- Determine whether a source concerns Guinea-Bissau and the population universe required by the task.
- Compare demographic series after checking dates, definitions, geographic boundaries and estimation methods.
- Summarise population structure and distribution while retaining uncertainty and source attribution.
- Examine whether births, deaths and migration plausibly account for a reported population change.
- Identify evidence gaps for Bissau, mainland areas and the Bijagós islands without assuming missing observations imply absent populations.
- Decide whether evidence supports a national comparison, a local planning use or only a qualified descriptive statement.
Hazards and failure modes required Filled
- Using outdated counts or treating projections as observations can distort planning and resource allocation.
- Incomplete coverage or inconsistent definitions can produce misleading comparisons between population groups or periods.
- Detailed population records can expose individuals or small communities when confidentiality protections are inadequate.
- Interpreting group statistics as personal characteristics can reinforce stereotypes and discriminatory decisions.
Standards and interfaces required Filled
- The United Nations Statistics Division publishes the Principles and Recommendations for Population and Housing Censuses as international guidance for producing comparable population statistics.
Context of use required Filled
- The demographics of Guinea-Bissau are studied through censuses, surveys, administrative records and population estimates.
- They inform public service planning, research and assessments of population distribution and change.
- Responsible use distinguishes reference dates, geographic coverage and observed counts from estimates or projections.

Open questions
- Which census and survey releases provide the most recent documented demographic baseline, and what coverage assessments accompany them?
- How should discrepancies between national statistical publications and international population estimates be reconciled for specific uses?
- Which administrative or settlement boundary changes require crosswalks, especially for Bissau and Bijagós reporting units?
- What comparable evidence exists for language, ethnicity and religion, and which categories or estimates lack a sufficiently documented measurement basis?
